Templated, reusable schedules so I don’t have to set up downtime for each kid individually. Allow overrides for holidays etc.

Apple let you press a button for ‘one more minute’ that seems impossible to disable.

Password management is horrible as a family, as is having to set up my fingerprint on all my kids’ devices to be able to help them with stuff without faff.

More generally, every time I have to set up any sort of account for my kids it’s absolute torture. Try to log in with Apple ID, can’t cos they’re a kid. Try to log in with a google account, remember Family Link doesn’t work for my normal account because it was set up for a domain, so log in as my other google account, set kid up, still doesn’t work.

Give me one place in my whole life to manage identity for my family, one that works, with permissions and downtime settings that integrate with every app and website in the world (including the half dozen each of my kids’ schools require us to use). I’ll pay loads of money for this.

The ability to make all content opt-in instead of opt-out would get you 90% of the way there. Very few services that I know of offer this. Most of them offer gating by age range into all content the service considers appropriate for that age, and most allow you to block specific content as well, but all I really want for my young kids is to know exactly what content is available to them because I have added it specifically.

Beyond that, there are some nice things you could do like a workflow for a kid to request new content and a parent to review and approve/deny it. But that's definitely a nice-to-have.

Forced IRC only hours.

Vastly smoother settings adjustment or profile selection per combo of kid/activity/device.
